Goals: the main objectives of the article are to describe the characteristics of the data librarian, to
underline the importance of their role at a time when Open Science practices are increasingly being
adopted in university libraries, and to provide guidelines for retraining library staff already offering
services to researchers in research institutions. Specifically, the aim is to define the profile of data
librarian staff and to highlight the knowledge and skills they must offer to the research community.
Methodology: A non-exhaustive bibliographic review was carried out in Google Scholar, Scopus, Web
of Science and Zenodo combining the terms Data librarian, Open Science and Library Documents
from the websites of official bodies and institutions such as the European Commission, Ligue des
Bibliothèques Européennes de Recherche (LIBER), International Federation of Library Associations and
Institutions (IFLA), American Library Association (ALA), United Nations Educational, Scientific and
Cultural Organization (UNESCO) and Conferencia de Rectores de las Universidades Españolas (CRUE)
were also consulted.
Results: Throughout the entire research process, the data librarian plays an essential role in supporting
data management. In addition to the traditional skills required of librarians in general, data librarians must
have specific training to understand the research cycle in depth, a thorough knowledge of data
management and curation, and advanced technological and communication skills. Data librarians offer a
very wide and flexible range of services that meets the needs of each stage of the research.
